Re: [Tagging] RFC - Hazards - Pedestrian hazard

2020-12-06 Thread Brian M. Sperlongano
Ah yes, I temporarily forgot that we have other street view sites!  Thank
you for that subtle nudge.

I pulled up this [1] example at random, which is tagged in the map with
hazard=cyclists (on a stretch of way).  I assume this means (in this
specific case) "cyclists enter the roadway 100m ahead".  Next randomly
selected example [2] in Poland is a spot where a signed bike lane ends and
cyclists begin sharing the road with cars.

Now admittedly, 239 usages is a tiny amount of existing usage, but the way
I've described it in the proposal seems consistent with how mappers have
actually used this tag so far (bike in road hazards).  I also recently
changed over the example image in the proposal to a MUTCD-style "share the
road with bicycles" sign, which is a less ambiguous descriptor than the
red-triangle-with-a-bicycle variants.

I tend to favor formalizing existing usage rather than inventing new tags,
as well as more concise tags instead of verbose ones.  If there is a
consensus that hazard=cyclists will be misused if approved and documented,
we can change it to something invented like hazard=cyclists_in_road.  If
there isn't a consensus on what to do with this value, I would just drop
this particular value from the proposal as a future problem in order to
approve the set of tags that we all agree on!

I have looked it up, and until 2013 the sign was called “crossing cyclists” 
while it is now called “cyclists”. It is typically set up before bicycle 
crossings or before a separate  cycleway merges with the road.

The largest existing use of hazard=cyclists is in Germany.  There is no
Google StreetView in Germany, but from the small number examples [1] I
looked at, it seems like this tag is being used for "cyclists in the road"
hazards and not "cyclist crossings".  There were only 10 usages of the tag
(out of a few hundred) that were combined with highway=crossing.  So it
does seem that the way this is being used in actual practice is
hazard=cyclists for "cyclist in the road" hazards and highway=crossing +
bicycle=yes for cyclist crossings.  As long as the use of this tag is
properly documented (which I will strive earnestly to ensure), and with
links to the cyclist crossing wiki page, this distinction seems sufficient.

Over 160,000 cyclist crossings have been tagged (highway=crossing +
bicycle=*), and it is well-established tagging, but this is clearly a
different case!  In addition to being useful to motorists ("watch out for
bicycles!"), conversely it is also useful to cyclists ("this is a more
dangerous than usual place to ride!").

Doing it to you again! :-)

https://www.google.com.au/maps/@-28.128994,153.4847037,3a,75y,327.54h,51.22t/data=!3m6!1e1!3m4!1sSXoyhtDrthUQ45j0cSdQ4g!2e0!7i13312!8i6656?hl=en

Since these images were taken, signage has also been put up warning of
cyclists on road, in addition to the roadway markings.

Thanks

in my area the typical situation for a cyclists hazard sign is actually
cycleways crossing the street. I cannot remember having seen such signage
for places where cyclists are using the road. If we want to distinguish
these 2 cases I suggest to use more explicit values like
hazard=cyclists_on_the_road and hazard=bicycle_crossing, because
hazard=cyclists does not make it clear and would be used in all bicycle
related "hazardous" situations.

[Tagging] RFC - Hazards - Pedestrian hazard

2020-12-06 Thread Brian M. Sperlongano
The hazard proposal [1] currently proposes hazard=cyclists as a way to tag
a signed area in which motorists should watch for or share the road with
cyclists.  Note that this is explicitly different from a cyclist crossing,
which is currently covered by highway=crossing.

It was suggested by a commenter on the talk page that hazard=pedestrian
(which has a few hundred usages) should be added as well, to indicate a
hazard of pedestrians sharing the road with cars.  Is anyone aware of
examples of this that are NOT pedestrian *crossings*?  The searching I've
done for pedestrian hazards all seem to turn up with crosswalk signs, which
I feel are out of scope for the hazard= key.
